PREPS Score of Gutierrez et al for Early Laparotomy of an Adult with Traumatic Injury

Description

Gutierrez et al reported the PREPS (Prehospital Preparation for Surgery) score to identify an adult trauma patient who requires an early laparotomy. This partially depends on prehospital data. The authors are from University of Southern California in Los Angeles.

Patient selection: adult trauma

Outcome: laparotomy within 2 hours of arrival at the trauma center

Parameter:

(1) sex

(2) blunt mechanism

(3) penetrating mechanism

(4) Glasgow Coma Scale (GCS) from 3 to 15

(5) systolic blood pressure in mm Hg

(6) chest wall deformity or instability

(7) pelvic fracture

Parameter	Finding	Points
sex	female	0
	male	2
blunt mechanism	high risk	2
	low or moderate risk	0
	none	0
penetrating trauma	head, neck, torso or limbs proximal elbow or knee	10
	other	0
	none	0
GCS	14 or 15	0
	3 to 13	1
systolic blood pressure	>= 90 mm Hg	0
	< 90 mm Hg	2
chest wall instability	no	0
	yes	2
pelvic fracture	no	0
	yes	1

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 20

• A cut-off value was not seen in the paper.

Performance:

• The area under the ROC curve is 0.79 in the derivation and 0.78 in the validation cohorts.
